Abstract
Disclosed is a high strength, self-lubricating, non-metallic gear which requires no lubrication when running with a metallic gear. The gears are secured to their shafts with keyless retaining devices, and the gear set is cut with a non-standard tooth form to provide superior power transmission performance.
